CHURN.

SPECIFICATION forming part of Letters Patent No. 238,017, dated February22, 18 81. Application filed December 20, 1880. (ModeL) Patented inCanada July 15, 1880.

To all whom it may concern:

Be itknown that I, FRED ALDRED, of Glencoe, Province of Ontario,Dominion of Canada, have invented a new and useful Improvement in Churns, (for which I have received Letters Patent in Canada, No. 11,498,dated July 15, 1880,) of which the followingis a specification.

Figure 1 isa sectional side elevation of the improvement. Fig. 2 is asectional end elevation. Fig. 3 is an end elevation.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to furnish churns so constructed thatthey can be easily operated and will bring the butter in a very shorttime.

A represents the churn-body, the bottom and top of which are horizontal,the sides vertical, and the ends semi-cylindrical in form. In the middlepart of the top of the churnbody A is formed a'large opening forconvenience in putting in the milk and taking out the butter, whichopening is surrounded by a flange, B, and is closed by a cover, C,fitting into the space within the flanges B and resting upon the top ofthe. churn-body at the sides of the opening. The cover C is providedwith a knob or other handle, D, for convenience in removing andreplacing the said cover.

To the ends of the churn-body A, and above its central line, areattached two sockets, E, to receive the ends of the springs F. Ifdesired, the sockets E can be made in the form of pairs of hooks toreceive the end parts of cross-pins N. attached to the ends of thesprings F. The latter construction is shown in t-hedrawin gs, and ispreferred, as giving the springs a greater freedom of movement. Thelower ends of the springs F are secured, by bolts or other suitablemeans, to a frame or platform, G, which rests upon the floor or othersuitable support, and may be secured to the floor by hand-screws H orother convenient means, to prevent it from moving when the churn isbeing used.

The springs F are made 8 shape, as shown in Fig. 1, the upper ends beingso formed as to correspond with the curves of the ends of the churn-bodyA to give greater elasticity to the springs, and to allow the churn-bodyto have a longer swing.

To the upper parts of the ends of the churnbody A are attached handlesI, for convenience in operating the churn.

In the inner surface of the sides of the churn-body A, at the corners ofthe opening in the top of the said churn-body, are formed short verticalgrooves J to receive the ends of one or more cross-bars, K. i

To the cross-bars K are attached parallel bars or fingers L, whichproject to, or nearly to, the bottom of the churn-body A, as shown inFigs. 1 and 2.

If desired, the dashers K L may be made in the form of perforated orslotted boards or plates, in which case the grooves J may extend to, ornearly to, the bottom of the churnbody A. The dashers K L are secured inplace by the cover C, or they may be permanently attached to thechurn-body; butl prefer to make them removable for convenience incleaning the churn-body.

In using the churn the milk is poured in, and the cover C is put on. Theoperator then takes hold of one of the handles I, and moves thechurn-body A forward and back longitudinally, which change of motion, inconnection with the semi-cylindrical form of the ends of the churn-body,causes the milk to rise and fall or be thrown back toward the middlepart of the. churn body, and the dashers K L, through the openings ofwhich the milk has to pass, throw the milk into violent agitation andbring the butter in a very short time. \Vhen the churning has beenfinished and the butter taken out, the butter-milk is drawn out throughan aperture in the lower part of the side of the churn-body A, whichaperture is closed by a plug, M, a faucet, or other suitable means.

Having thus fully described my invention, I claim as new, and desire tosecure by Letters Pat-ent- 1. In a swinging churn, the supportingspringsF, made in S shape, and attached to the ends of the churn above thecentral line, substantially as herein shown and described, whereby thechurn-body is supported and allowed tovibrate, as set forth. I

2. In a swinging churn, the combination, with the churn'body A, of theS-shaped supportin g-sprin gs F, provided with cross-pins N, and thehook-sockets. E, substantially as herein shown and described, wherebythe churnbody is allowed to vibrate freely, as set forth.
